This course is designed to give a basic understanding of vehicle systems and how they interact with each other to cause common vibration complaints. These systems include the complete drivetrain and the vehicle. This class will also provide a basic understanding of the operation and overhaul of Spicer Heavy-Duty Drive Axles. Finally, this class will provide a thorough understanding of the operation and overhaul of various Fuller® clutch models.

During the vehicle vibration classroom portion, technicians will be exposed to the theory of operation and troubleshooting procedures for efficiently correcting vibration complaints. Technicians will be instructed on the calculation of joint working angles. During the drive axle classroom portion, technicians will be exposed to the theory of operation, power flow, wheel differential systems and an in-depth review of inter-axle differentials. Finally, during the clutch classroom portion, technicians will be exposed to clutch basics including nomenclature and clutch theory. Incorporated throughout this training is a thorough explanation of the operation of a clutch and how to service specific clutches including the Solo®, Easy-Pedal™, and DM models.

Technicians will also learn the latest troubleshooting techniques and cover common, everyday experiences in repairing vibration complaints. In addition, the technicians will be exposed to the latest industry diagnostic tools including the (DVA) Driveline Vibration Tool.  Technicians will review a descriptive failure analysis section consisting of various axle components to increase their understanding of service life and various failure modes of the components.

Upon completion of the classroom presentation, the overhaul portion will continue into a hands-on tear down and reassembly of the DS-404 and the S-170/190 models using the correct tools and techniques. Analysis of clutch construction and design will be reviewed in detail.
